> This can be considered as continuation of MYFACES-3202. Implements
> requirement "any time there is an error the user should see not just a
> cryptic stack trace, but the EL expression that was being evaluated -
> including the part of the EL expression that triggered the problem"
> Example:
> <f:actionListener type="com.foo.Bazz" /> is represented as
> org.apache.myfaces.view.facelets.tag.jsf.core.ValueChangeListenerHandler.LazyValueChangeListener
> instance. But if look in code, you see simple
> valueChangeListener.processValueChange(event); without try catch. If
> exception occurs, no facelets Location or TagAttribute context is available
> and therefore exception handling mechanism is not able to output info about
> problematic XML tag.
> Use types created as part of MYFACES-3202 (ContextAware, LocationAware .. );
> create something like ExecuteTemplate and ExecuteCallback and perform all
> operation with proper context.
